Congratz! mines currently less than 30k but hoping to keep it forever - the way I treat my cars and the great luck I have had with mustangs in my life I'm confident I can get it to last longer than I do. I put about 5k a year.

my 98 v6 was at 190k miles when I traded in for my s197, rang strong the whole time i had it, never let me down or gave any problems, the only things i had to replace were general maintenance items.
